Letters Patent No. 94,217, dated August 31, 1869.

IMPRO'VED STUMP-EXTRACTOR.

The Schedule referred to in these Letters Patent and making p art of thesama.

To whom it may concern:

Be it known that we, JOHN A'. KAUssLEe and HORACE B. COOK, of WhitePigeon, in the county of St. Joseph, and State of Michigan, haveinvented a new and useful Improvement in Stump and Grub-EX- tractors;and we do declare that the following is a true and accurate descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, and being a part of thisspecification.

Figure 1 is a perspective view of our invention.

Figure 2 is a detached View of the lever and swivel.

Figure 3 is a view' of the adjustable grapnel.,

Like letters refer to like parts in each ligure.

The nature of this'invention relates to an improved construction of anapparatus for extracting heavy stumps or comparativelyV lighter' grubs;and consists of a suitable frame, so` attached to a carriage that it maybe brought into' use when required, or elevated upon the trucks fortransportation; also in an adjustable lever, suspended by means of aproper swivel' to the top cross-bar of the frame, in such a mannerthatthe fulcrum-point may be changed, thereby giving the operator thenecessary leverage to do the required work; also in a suitable devicefor raising the outer end of the lever, when desired; also in a novelclamp for grasping grubs, when the apparatus is used;

for grubbing,. and in a new, novel, and'ingenious arrangement of all itsvarious parts, as more fullyl hereinafter described.

A, in the drawing, represents a suitable frame, composed of the bottomplates a, upright posts b; cross-bar c, and braces fl, properly puttogether and secured.

To the upright posts bare secured the metallic straps B, in suoli amanner as to formloops or guides, within which the standards C have avertical movef ment.

To the foot of these standards are secured, -upon proper axles orjournals, the wheels D.

Journalled at each end, to these standards C, is the rock-shaft E, towhich are secured the cams e.

A semi-rotation of this rock-shaft is obtained by means ot' the compoundlever F, lwhich is properlyv fastened for that purpose to one of theupright posts b, and to the rock-shaft.'

This partial rotation lcompels the cams e to engage with and against thepins f, which are` driven into the inner faces of the upright po'sts b,thereby raising the wholeframefrom oti' the ground and upon the stand?ards and wheels, ready to be transported to any desired point.

'Suspended from the cross-bar c, by means of double swivel clevis G, isthe lever H, provided, upon its under side, with a series of pins, g, orsuitable notches,

'the stop in place.

lever, and heldin any desired position by the notches or pms t.

From this clevis is suspended a proper chain o r rope, J, the lower endof which is designed to be passed around a stump to be extracted fromthe ground.

Then the hookin the bottoin ofthe block j is secured to the chain nearthe stump,.and power being applied, by means of the rope h, the stump islifted from out the ground.

When the fulcrum-point is changed from the centre to a point nearer oneend of the lever, it becomes necessary t'o adopt some device to raisethe longer arn of the lever. This is done by erecting upon and securingto the cross-bar c a proper standard, K, provided at its top with asheave, over which runs the rope lc, l

which is secured to the longer arm of the lever in such a manner that itcan easily be raised, when desired, b v pulling upon the rope It.

When the apparatus is designedlfor pulling small stumps or grubs, whichvary in size, and still are so small 'that the chain J cannotconveniently be secured to them, a clamp, L, may b e attached to thechain in such a manner that the clamp may be passed around the grub.

This clamp. is constructed of a strap of iron, madev in the form shownin the drawings, and its upper edges provided with seri-ations or teethl, and the clamp o r grapnelis secured to the chain by the triangularlink m.

After this clamp has been placed around the grub, the stop n, providedwith bail o, is 'placed on top of the grapneh lthe stop n being next thetwo, while the bail o engages with any of the series of teeth l, to'holdThe book in the bottom of the block j is thensecured to the bail c, andthe power applied as in pulling larger stumps.

The -grapnel or clamp, constructed `in the manner described, can beadjusted, by means of the teeth and stop, to tit any-sized grub.

- What we claim as our invention, and desire to secure by LettersPatent, is-

l. The vclamp L, when constructed and operating substantially as and forthe purposes described. l

2. The rock-shaft E, cams c, compound lever F, and

pins f, or their lequivalents, in connection with the constructed, andoperating substantially as and for the frame A, standards O, and wheelsID, when arranged purposes herein set forth and shown.

and operating substantially as and for the purposes J. A. KAUSSLER.herein speeiied. H. B. COOK.
